TPS54525 Question about supply current

Other Parts Discussed in Thread: TPS54525

On the datasheet on TPS54525, I_Vin(Operating - non-switching supply current) and I_Vin(Shutdown supply acrrent) are specified as follows;

I_Vin(Operating - non-switching supply current) : 900uA_Typ, 1400uA_Max

I_Vinsdn(Shutdown supply acrrent) : 3.6uA_Typ, 10uA_Max

Above value are specified where Vin=12V. In case of Vin=5V, the value of I_Vin and I_Vinsdn are same with Vin=12V?

When you measured it, did you force the IC not to switch by forcing VFB to 0.8 V? We may have data for that case, I'll check.

I checked my data file. I only have the Vin = 12 V case. How urgent is your need for 5 Vdata?

0 JohnTucker over 11 years ago in reply to JohnTucker

There is additional data for Vin = 18 V. The current increases slightly, about 15 uA. I did not see any data for Vin below 12 V.

John,

Thanks for your information.
